This feels like it should be pretty straightforward but I’m out of ideas.

I’m trying to run what I feel like is a fairly simple script to take a folder of markdown files with text and convert then into a single running .docx file. For some reason I keep getting the same error issue no matter what I do.

Traceback (most recent call last):
  File "c:PATHmarkdown_conversion.py", line 52, in <module>
    append_docx_to_existing(existing_docx, docx_file)
  File "c:PATHmarkdown_conversion.py", line 25, in append_docx_to_existing
    doc = Document(existing_file)
          ^^^^^^^^^^^^^^^^^^^^^^^

    raise PackageNotFoundError("Package not found at '%s'" % pkg_file)

I have verified the correct path, tried creating new files and restarted multiple times. This feels like it should not be too complicated.
